T0' ALL WHOM IT MAY ACONCERN:

Be it known that I, Tunonorin GniiNDMANN, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented a new and improved Distillng-Apparatus; and I do hereby declare that the .following is a full, clear, and enact description thereof, which will enable others skilled in tho art to malte and use the same, reference being had to the accompanying drawings, forming part ot' this specification.

Figure 1 represents a sectional elevation of my improved distilling-apparaltus.

Figure 2 is a planer top view of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and sim-ple device for distilli'ng,condensing, and cooling mash, beer, cider, volatile oil, or other suitable liquids, adaptable more particularly for distilling on'a small scale.

The invention consists'tin arranging above the retort a small vessel, into which the vapors pass, and-whence they are conducted tothe cholcr. This small vessel c ommunicates, by means of two pipes, with the rctort, tov prevent the ovcrboiling of the liquid in the retort, thereby producing much more and purer alcoholfrom the same amount of mash than could.b e produced by the apparatus now in u sc.- The cover ofthe small vessel is made hollow, so that water can be. held in it to cool thevapors, and to condense'thosc that are not quite pure.

A represents a rctortinadc of suitable material. Bis a small vessel arranged above the retort, and commnnca'tmg with the same means of two pipes, aandb. The'pipc 'a extends from-the centre ofthe domeshaped cover, c, of the retort, to the side of the vessel, its end entering the vessel B ahoutmidway between the cover and bottom of the same, as shown in fig. 1. The Aother pipe, b, reaches'from a lower part ofthe cover c to the bottom, d, of the vessel B.'

Any vapors arising from the retort enter the upper part of the' vessel B through the pipe a, while those that have been condensed again in the vessel B return to the retort through the pipe b.

If the heat under` the retort is too strong, so that theliquid overboils in the rctorts, 1t will enter the vessel B through one o r both the pipes a and 6,'and will remain therein until it is cooled olf. The exposing the liquids tothe atinosphere'when they overboil, as uis usually donc in Vordinary retorts, is by this arrangement avoided, and the consequent waste of material.

The cover e of the vessel B is made concave, or is surrounded by a'ring, f, so as to form an open vessel or pan, into which water can he made to ilow from a reservoir, lC, through a pipe, g. :The covering-plateI of the vessel will thereby be cooled, and the vapors not light enough to pass directly oil' to the coolerare again condensed and returned to the retort. Thereby n'one but the pure vapors will be retained for further condensation y in the cooling-apparatus.

D is a pipe connecting the upper part of the vcssclB with a suitable cooler, E.

The cooler may be of suitable construction. That represented in the drawing consists of three vessels, la, z', and .7', arranged one within -the other, being thc cooling-space, the water or coolinglliquid circulating around it in h and I i The condensed pure alcohol is drawn oii the vessel t' through a pipe, 7c.

The water is, by Aa pipe, Z, brought to the lower part ofthe vessels h and j, and, rising, llows off from their upper part throughs. pipe, fm.

' I claim as new, and desireto secure by Letters Patent- 1. The vessel B, when connected with the -upper part of the retort by means of pipes a and b, and whenV provided with a dish-shaped cooling-cover, e, substantially as and for the purpose herein shown and described.

2.- The retort A and vessel B, when made and arranged as s'et. forth, in combination with a cooler, E, as described. A
